Hi

The Answer is

4.Compilation and output of "Not equal 10"

Because The else part will be executed insted of and condition the b1=false.

The + operator with the String always concatinate the String

and the variable

Hello Payal,

I think it is not okay from you to let the forum guys answer all your exam question without approve by points.
